It consists of an array of zener diodes with each diode having a constant voltage drop. It is designed to deliver reliable and accurate voltage regulation over a wide temperature range and across multiple frequency ranges.

Application Field

The DZ23C47-E3-18 is suitable for various applications, including logic circuits, voltage regulation, and temperature monitoring. It has compatibility with TTL logic levels, making it suitable for use in digital circuits, as well as in microcontroller and other devices which need constant voltage regulation. In addition, it can be used for temperature sensing and for burn-in applications.

Working Principle

The DZ23C47-E3-18 consists of an array of zener diode junctions with a low resistance connecting each diode junction. The junctions are connected in series, which allows them to have a constant voltage drop. When a voltage is applied to the array, the constant voltage drop of the zener diodes regulates the maximum voltage, preventing it from exceeding a predefined threshold.

A connected 8-bit shift register allows the voltage regulator to program each output individually, allowing the implementation of adjustable voltage regulation. Additionally, the low impedance of the components offers a low dropout voltage when compared to traditional voltage regulators.
